Abstract: Disclosed is a bubble lamp for quasi bubble flow. A buffer made of a transparent material having an excellent heat conduction effect and impact moderating performance is configured on the top of the bulb configured on the main body of the bubble lamp or on the bottom of the glass tube configured on the upper cover, and the casing made of a transparent and no-easily-broken material is put around the glass tube, thereby abutting the glass tube against the top of the bulb across the buffer when the upper cover is covered on and coupled to the main body, allowing both the glass-made bulb and glass tube to be buffered by the butter and thus to block or decrease an impact when a contact force is too large upon assembly, and preventing the bulb or glass tube from being broken.

Abstract: A luminous keyboard includes a keypad module, plural light-emitting elements, a light guide plate and a reflecting plate. The reflecting plate has plural light amount control structures. The light amount control structures are disposed on the reflecting plate, and located near the corresponding light-emitting elements. When the plural light-emitting elements emit light beams, the portions of the light beams that are not subjected to total internal reflection within the light guide plate are reflected by the reflecting plate. When the light beams are transferred through the light amount control structure, the reflected fraction of the light beams is reduced. Since the light beams are not very centralized, the problem of generating bright spots will be diminished.
